Predictive factors of catch-up growth in term, small for gestational age infants: a two-year prospective observational study in Algeria.

Objectives: Most small for gestational age (SGA) infants show catch-up growth but the minority who do not may benefit from growth-promoting treatment. We determined the prevalence of, and risk factors for, failure to show catch-up growth in term SGA infants.

Methods: Prospective observational study of infants born at 37-42 weeks gestation between December 2012 and March 2014 with birth weight <10th percentile.

Inborn Errors of Immunity in Algerian Children and Adults: A Single-Center Experience Over a Period of 13 Years (2008-2021).

Background: Inborn errors of immunity (IEI) predispose patients to various infectious and non-infectious complications. Thanks to the development and expanding use of flow cytometry and increased awareness, the diagnostic rate of IEI has markedly increased in Algeria the last decade.

Aim: This study aimed to describe a large cohort of Algerian patients with probable IEI and to determine their clinical characteristics and outcomes.

Does omeprazole improve asthma-control in poorly-controlled asthmatic children with gastro-esophageal reflux.

Objectives: The role of gastro-esophageal reflux disease (GERD) in poorly controlled asthma is often mentioned, but published studies have presented discordant results. Our main objective was to assess the effectiveness of GERD treatment in controlling asthma in children.

Methods: We conducted a prospective study including poorly controlled asthmatic children aged 4 to 16 years.

F-BAR domain only protein 1 (FCHO1) deficiency is a novel cause of combined immune deficiency in human subjects.

FCHO1 deficiency is a novel autosomal recessive combined immune deficiency with impaired clathrin-mediated endocytosis

Prevalence of BTK mutations in male Algerian patterns with agammaglobulinemia and severe B cell lymphopenia.

X linked agammaglobulinemia (XLA) is the first described primary immunodeficiency and the most common form of agammaglobulinemia. It is characterized by susceptibility to recurrent infections, profound decrease of all immunoglobulin isotypes and very low level of B lymphocytes in peripheral blood. The disorder is caused by mutations in the Bruton's Tyrosine Kinase (BTK).

Clinical, immunological and genetic features in eleven Algerian patients with major histocompatibility complex class II expression deficiency.

Presenting processed antigens to CD4+ lymphocytes during the immune response involves major histocompatibility complex class II molecules. MHC class II genes transcription is regulated by four transcription factors: CIITA, RFXANK, RFX5 and RFXAP. Defects in these factors result in major histocompatibility complex class II expression deficiency, a primary combined immunodeficiency frequent in North Africa.
